pkg aparently not respecting subversion make.conf settings

[Simon Wright]

Hi all

I've recently set up poudriere and pkg on a 9.2 amd64 box. This has 
worked well for the last month or so. However I have just tried to 
downgrade subversion to 1.7x from 1.8x to support querying my 
network /usr/src /usr/ports that is setup on another box that only 
runs subversion 1.7.

As per updating, I set WITH_SUBVERSION_VER=17 in /etc/make.conf and 
also in /usr/local/etc/poudriere.d/make.conf, added subversion17 to 
the list of packages to be built and removed portdowngrade from the 
repository with:

poudriere bulk -j freebsd:9:x86:64 -C ports-mgmt/portdowngrade

portdowngrade is removed from the repo and then the rebuild begins:

<snipped>

---Begin make.conf---
USE_PACKAGE_DEPENDS=yes
BATCH=yes
WRKDIRPREFIX=/wrkdirs
PACKAGES=/packages
DISTDIR=/distfiles
#### /usr/local/etc/poudriere.d/make.conf ####

WITH_SUBVERSION_VER=17

DISABLE_MAKE_JOBS=poudriere
---End make.conf---

It looks as though pkg is not recognising the WITH_SUBVERSION_VER=17 
variable and instead pulling in version 1.8 which is the default.

There are no options in portdowngrade to use a specific version of 
subversion.

Can anyone offer any suggestions to let me build a package of 
portdowngrade that uses my desired version of subversion or see what 
I've done wrong?

Thanks!
